Multi-select question
The small ribosomal subunits have
A) E site
B) P site
C) A site
D) mRNA bind site
Small ribosome subunit or 40S binds to mRNA during translation. E site, P site and A sites are present in the large subunit or 60S subunit of the ribosomes.
So answer is option D) mRNA bind site

Where are the ribosomal subunits assembled? Select one: a. Nucleus b. Nucleoid c. Nucleolus d. Nuclear envelope
Place the events of Translation in bacteria into the correct order. The large ribosomal subunit associates with the small subunit and mRNA. The ribosome shifts along the mRNA in the 5' to 3' direction, moving the tRNA from the aminoacyl (A) site into the peptidyl (P) site. The tRNA in the peptidyl (P) site shifts to the E site and leaves the ribosome. The next charged tRNA enters the open aminoacyl (A site of the ribosome. Aminoacyltransferase attaches the amino...

Which of the following statements best describes the initiation of translation? A tRNA with the anticodon, AUG, enters the ribosomal complex and binds to the mRNA at the A site. b) The large and small ribosomal subunits scan the mRNA in the 3'-5 direction until the promoter is reached. The mRNA containing the start codon, AUG, sits at the P site and forms a complex with the corresponding tRNA, and the large and small ribosomal subunits. d) The mRNA attaches...
answer all the questions 18) A mutation occurs such that a spliceosome cannot remove one of the introns in a gene. What effect will this have on the gene? Translation will continue, but a nonfunctional protein will be made b) Translation will continue and will skip the intron sequence c) It will have no effect; the gene will be transcribed and translated into protein d) Transcription will terminate easily and the protein will not be made 19. During the process...
36. Which of the following is true for the ribosomes (rRNA) found in Prokaryotic cells? They are: a) made of DNA and protejn, b) the active site in carbohydrate synthesis, c) subunits that use mRNA as the directions for primary structure of protein attached to the endoplasmic reticulum, e) used to synthesize DNA by dehydration synthesis. answer the question and give a why the circled answer wasn't correct 36. Which of the following is true for the ribosomes (rRNA) found...
In Bacteria, translation of nascent RNA transcripts is often initiated before transcription is terminated. When this occurs: Select one: a. RNA is transcribed 3'=>5' and amino acids are added to the carboxy terminus of the growing polypeptide as the ribosome moves 5' => 3' along the mRNA b. RNA is transcribed 5'->3' and amino acids are added to the amino terminus of the growing polypeptide as the ribosome moves 3'=> 5' along the mRNA c. RNA is transcribed 3'=> 5'...
QUESTION 35 Tetracycline is an antibiotic used to treat bacterial infections in humans because it prevents the growth and spread of bacteria. This drug is known to bind strongly and specifically to the A site in the 30S ribosomal subunit. Based on this information you would expect that: a. tetracycline does not affect translation in eukaryotic cells. b. tetracycline inhibits RNA splicing in prokarytes. c. tetracycline will prevent the small ribosomal subunit from binding to the Shine-Dalgarno sequence. d. tetracycline...
